Thanks , I see why now.
I was hoping to Grind it my self, By hand, A little at a time ??, So as not to get it too hot.
I have a few ways of holding grinding paper.
I don't think it has to be dead straight, Because the ground bit will have to face out of the case for the lip to work.
It's only an 8th of an inch
.
You have now worried me about using the magnetic boring machine, To bore the Bigend hole,
Will the Flywheels become magnetic ?.
Funny thing is I am now too old to use the extra 60cc, It is just a silly dream I have been putting off for years.
But with the Wife stuck at home, Now may be the time to have a go.
Many Thanks Marcus, But you are a bit too far from me, I don't travel well, Don't know how I used to get down to Devon to Ron's, But the Silly Sod has now moved to London.
Cheers Bill.
